However, being able to just use portions of the text verbatim (with
the appropriate notice), e.g. when aligning something with the
standard,
does save re-inventing the wheel and risking imperfect paraphrasing...

Does the notice have to be place in the AUTHORS section? And how big is
it?

Whoever follows up with the IEEE (Hiten seemed to be on the ball) will
presumably find out the precise requirements; all I can say is that they
didn't look too burdensome judging by what the Linux folks have released.

Guys, hold your horses for now. :-) I am gonna get in contact
with Jacques Vidrine (nectar@) of Camp FreeBSD and coordinate
this stuff with him.
